SEMESTER SPRING 2012 Introduction to Psychology (PSY101) Assignment No. 1 Due Date: April 19, 2012 Marks: 20 Assignment: “Reinforcement” Reinforcement, whether positive or negative, strengthens behavior. A behavior which is strengthened through the process of reinforcement is called “Operant Behavior”. Positive reinforcer is a stimulus whose introduction brings about an increase in the preceding response while negative reinforcer is a stimulus whose removal reinforces and leads to a higher likelihood that the response bringing about this removal will be repeated. Part 1 Focusing on the above mentioned details, you are supposed to read the following situations in detail to pick out the followings: Type of reinforcement (1+1+1+1+1+1+1) · What kind of reinforcement has been narrated in situation, positive or negative? Reinforces (.5+.5+.5+.5+.5+.5+.5) · Which specific reinforcer is serving to strengthen the behavior? Strengthened Behaviors (.5+.5+.5+.5+.5+.5+.5) · Which specific behavior is being strengthened, pick out the specific behavior from the situation? You are supposed to record your answers in the following table given at the end. Situation 1: A two years old child has a tantrum (crying and screaming) in the grocery store when he demands candy and his mother says no. His mother eventually buys him a candy and he stops his tantrum. As a result, his mother is more likely to give him a candy when he demands it and has a tantrum. Situation 2: Little Ahmed cries at night after being put to bed and his parents come to his room to comfort him and calm him down. As a result, Ahmed now cries more often at bed time. Situation 3: When a chef cooks steaks, it creates smoke. He turns on the exhaust fan, and the smoke is sucked out of the kitchen. He is now more likely to turn exhaust fan when he cooks steaks. Situation 4: A teacher smiles at Hassan and praises him when he stays at his seat and pays attention to the class work in the class room. As a result, Hassan started to show good class room behavior. Situation 5: Instead of paying workers by the hour, a bicycle manufacturing company begins paying piece rate, in which workers on the assembly line earn a certain amount of money for each bicycle that they assemble. As a result, the workers assemble more bicycles each day and earn more money. Situation 6: A college student is answering study guide questions for her Psychology class. When she can’t figure out an answer to a question, she asks her friend who already took the class. Her friend tells her the correct answer. As a result, she is more likely to ask her friend for an answer to question she does not know. Situation 7: A woman waiting for the bus opens up her umbrella when it rains. The umbrella keeps the rain from hitting her. Now she always opens up her umbrella when it rains.
